Soloing Snowblind is entirely luck based since his roar 1-shots you with 10 stacks and enrage (and does way too much damage if you cannot heal from it outside enrage)
Just gotta hope you resist all those you cannot CC-break / Force Barrier / Resilience out.

Both gj anyways, I tried it on my shadow tank and just Force Cloaked after seeing that I couldn't possibly outheal his enrage.
